This application constitutes a continuation of our copending commonlyassigned application for US. Letters Patent, Serial No. 70,315, filedNovember 21, 1960.

This invention relates in general to new and useful improvements inrefueling equipment, and more particularly to a nozzle and adapterassembly of the type wherein the nozzle is readily released from theadapter.

In the high speed refueling of aircraft, there has been provided in ahydrant system wherein fuel is provided under pressure at a refuelingarea, and the hydrant is connected to the tank of the aircraft by meansof a hose having nozzles at opposite ends thereof, the hose nozzlesbeing readily engaged and disengaged from the hydrants whereby a hosemay be transported from one hydrant to another and used for therefueling of various aircraft at different hydrant systems. Thisinvention in particular pertains to the construction of a nozzle and theadapter for the nozzle whereby the connection between the refueling hoseand either a hydrant or an aircraft tank may be readily accomplished.

In accordance with the foregoing, it is a primary object of theinvention to provide a nozzle to adapter connection wherein theconnection may be easily and quickly made and broken and at the sametime, is of a nature wherein a tight seal is provided between the nozzleand the adapter to prevent the leakage of fuel during a refuelingoperation.

Another object of the invention is to provide a novel connection betweena nozzle and an adapter, with the connection including a collar which isslidable relative to the nozzle and which controls the interlocking ofthe nozzle with the adapter, the collar also controlling the opening ofa valve of a nozzle wherein the collar prevents the opening of thenozzle valve until such time as the collar is seated in a nozzle toadapter locking position and the connection between the nozzle and thevalve control also preventing movement of the collar to a nozzlereleasing position until such time as the nozzle valve is in a closedposition.

Another object of the invention is to provide a novel nozzle and adapterassembly wherein the nozzle has an interlock with the adapter assemblyto prevent the accidental disconnection thereof, the interlock betweenthe nozzle and the adapter including a collar which prevent thereleasing of the nozzle until the collar is manually withdrawn, andthere being provided a connection between the collar of the nozzle andcontrol means for a valve and nozzle wherein the valve of the nozzlecannot be opened until the collar is in a nozzle to adapter lockingposition and the collar cannot be withdrawn to release the nozzle untilsuch time as the nozzle valve has been closed, and there further beingprovided means which prevents the movement of the collar from aretracted position to a projected nozzle locking position until suchtime as the nozzle is properly engaged with an adapter, therebypreventing the opening of the nozzle valve until such time as the nozzleis fully seated and interlocked relative to the adapter.

In the coupling of a nozzle to an adapter, it is absolutely necessarythat a tight seal be provided between the nozzle and the adapter toprevent the leakage of fuel between the two during a refuelingoperation. To this end, the nozzle is generally provided with a sealingring which 3,295,553 Patented Jan. 3, 1967 "ice engages the adapter toprevent the escape of fuel between the nozzle and the adapter. However,when the nozzle is moved relative to the adapter after the connectionbetween the :adapter and nozzle has been made, undesired twisting of thesealing ring occurs. Therefore, in accordance with this invention, it isa further object to provide a novel nozzle to adapter connection whereinthe nozzle is completely connected to the adapter but not sealedrelative thereto until such time as the refueling operation takes place,the sealing ring of the nozzle moving into engagement with the adapterto form a seal therewith as the valve of the nozzle is opened, therebypreventing wear on the sealing ring, which wear would result in animperfect seal.

A difiiculty encountered with the hydrant fueling system is that therefueling hose may be connected to a hydrant for a particular fuel,Whereas that fuel is not intended to be placed into the tanks of theparticular aircraft, various aircraft utilizing difierent fuels.Difiiculty is encountered when the person refueling the aircraft eitherdoes not know the type of fuel to be supplied to the aircraft or haserroneously connected the refueling hose to the wrong hydrant. It istherefore a still further object of the invention to provide a refuelingnozzle and adapter assembly having selector means whereby a nozzleintended to dispense a specific fuel can be coupled to only a specificadapter. In this manner, when an air- 7 craft tank is provided with aportion of the selector, only a hose having a nozzle with a matchingpart of the selector can be coupled to the aircraft tank. By the sametoken, if the same type of selector is placed on the nozzle at theopposite end of the hose, the hose can be only connected to a properhydrant. In this manner, it is impossible for a person refueling anaircraft to place the wrong fuel in the tank of the aircraft.

With the above, and other objects in view that will hereinafter appear,the nature of the invention will be more clearly understood by referenceto the following detailed description, the appended claims and theseveral views illustrated in the accompanying drawings:

Reference is now made to FIGURES 1 through 9 of the drawings wherein afirst form of the invention is illustrated. The assembly includes anozzle, generally referred to by the numeral 21, and an adapter,generally referred to by the numeral 22. The nozzle 21 includes a body23 which has a generally L-shaped fuel passage 24 therethrough. One endof the fuel passage 24 terminates in a fitting 25 to which a fuelinghose (not shown) may be connected. The opposite end of the fuel passage24 is normally closed by a valve member 26. The valve member 26 has asealing ring 27 to assure against the accidental escape of fuel throughthe fuel passage 24.

The valve member 26 is carried by a valve rod 28 which is secured to thevalve member 26 in any desired manner. The'valve rod 28 extends througha sleeve 29 seated in the nozzle body 23 in a bore 30 which opensrearwardly into a cavity 31 formed in the lower central rear portion ofthe nozzle body 23. The sleeve 29 is secured in place by means of asetscrew 32 and is provided with a sealing ring '33 which seals it tothe nozzle body 23. The sleeve 29 is also provided with a sealing ring34 which forms a seal between the valve rod 28 and the sleeve 29.

A shaft 35 is suitably rotatably journaled in the lower portion of thenozzle body 23 in the manner generally illustrated in FIGURE 1, theshaft 35 bridging the cavity 31. The shaft 35 carries a cam member 36which has a cam track 37 formed therein. A fitting 38 secured to therear or left end of the valve rod 28 is provided with a roller 40 whichis engaged in the cam track 37. It will be apparent that when the cam,36is rotatedin a clockwise direction, as shown in FIGURE 2, the valve rod28 will be moved to the right to move the valve member 26 to an unseatedposition whereby fuel may flow through the fuel passage 24. The shaft 35has a crank 41 secured thereto, with the crank 41 carrying a handle 42to facilitate the rotation of the shaft 35. The cam 36 is disposedwithin the cavity 31, and the lower portion of the cavity 31 is closedby a removable cover 43.

Referring now to FIGURE 3 in particular, it will be seen that theadapter 22 includes an adapter body 44 which is provided :at one endthereof with a flange 45 i which is utilized for the purpose of couplingthe adapter 22 to either a hydrant or a tank. The adapter body 44 alsoterminates at the left end thereof, as viewed in FIG- i URE 3, in aflange 46. A coupling sleeve, generally referred to by the numeral 47,is secured to and seated in the flange 46 by means of circumferentiallyspaced fas- I teners 48. The coupling collar 47 includes a sleeveportion 49 and a flange 50, the fasteners 48 passing through the flange50 and clamping the same against the flange 46. The coupling collar 47also includes an inwardly directed annular flange 51 which functions asa valve seat.

The adapter body 44 is provided adjacent the flange 45'with a spider 52which supports a sleeve 53. The spider 52 also supports a fuel flowdirecting cone 54. The sleeve 53 has a bore 55 therethrough with thebore 55 being of an increased diameter, as at 56, adjacent the left endof the bore 55. A suitable bushing 57 is seated in the enlarged portion56 of the bore 55.

The adapter 22 also includes a valve member 58 which has a sealing ring60 engageable with the valve seat 51 to close the adapter 22 againstflow of fuel therethrough. The valve member 58 is carried by a valve rod61 which is freely slidable in the bore 55 and in the bushing 57.

The valve rod 61 is suitably connected to the valve member 58, as at 62.A coil spring 63 is telescoped over the valve rod 61 and the sleeve 53and bears against the spider 52 at the right end thereof. The left endof the spring '63 bearsagainst the valve member 58 and continuouslyurges the valve member 58 towards the valve seat 51.

The sleeve portion 49 of the collar 47 has a specific externalconfiguration. It is to be understood that the sleeve 49 is of acircular cross-section throughout. The external surface has a first rampor cam portion 64 at the left end thereof. The exterior of the sleeve 49is then straight, as at 65, and then, there is a second ramp or camportion '66. Following the cam portion 66, the exterior of the sleeve 49is straight, as at 67, and then is provided with an annular recess 68into which connecting members, such as balls, may be seated. At thistime, it is pointed out that the flange 50 is sealed with respect to theadapter body 44 by means of a sealing ring 69.

Reference is now made to FIGURES 2 and 8 wherein it will be seen thatthe nozzle body 23 has a separate nose, generally referred to by thenumeral 70. The nose 70 is in the form of a cylindrical sleeve having aforward portion aligned with the corresponding part of the nozzle body23. The rear portion of the nose 70 is oflFset, as at 71, and istelescoped over the forward end of the nozzle body 23. The nose 70terminates at its rear end in an outwardly directed circumferentialflange 72. The rear portion of the nose 70 which is telescoped over theforward end of the nozzle body 23 is sealed relative thereto by means ofa sealing ring 73.

It is to be noted that the forward end of the nose 70 is provided withan inner valve seat 74 for engagement by the sealing ring 27 of thevalve member 26. It is also to be noted that the outer portion of theforward end of the nose 70 carries a sealing ring 75 which is held inplace by a retainer 76 which, in turn, is held in place by a snap ring77. The sealing ring 75, as is best illustrated in FIGURE 4, is intendedto engage the valve seat 51 of the collar 47 to form a seal between thenozzle 21 and the adapter 22.

The forward part of the nozzle body 23 is provided with longitudinalbores 78 in which balls 80 are disposed the balls 80 being urged forwardor to the right, as viewed in FIGURES 2 and 8, by springs 81 disposedWithin the bores 78. The balls 80 bear against the flange 72 of the nose70 and urge the nose 70 to the right.

A body extension, generally referred to by the numeral 82, is disposedoutwardly of the nose 70 and the forward end of the nozzle body 23. Thebody extension 82 is fixedly secured to the forward end of the nozzlebody 23 by means of circumferentially spaced fasteners 83 extendingthrough an outwardly directed annular flange 84 formed on the forwardpart of the nozzle body 23. This connection is best illustrated inFIGURE 2. The body extension 82 is provided adjacent the forward endthereof with a first set of circumferentially spaced balls 85 which aremounted in sockets configurated to restrict the inward movement of theballs 85 so that the balls 85 cannot move inwardly through the sockets86 and thus be lost. The balls 85 are intended to be seated on therecess 68 in the collar 47 to lock the nozzle 21 in a fixed positionwith respect to the adapter 22. The body extension 82 also includes aninternal annular abutment 79 in axially opposed relationship to theflange 72 of the nose 70 for preventing the separation of the nose 70from the nozzle body 23 under the biasing forces of the springs 81 whenthe valve 26 is open.

Referring once again to FIGURES 2 and 8 in particular, it will be seenthat a coupling assuring sleeve or collar, generally referred to by thenumeral 88, is disposed about the body extension 82. The sleeve 88 hasan inner recessed forward portion 89 in Which the outer portions of theballs 85 are received when the nozzle 21 is separate from the adapter22. The sleeve 88 serves to retain the balls 85 in their inwardlyprojected positions when the nozzle 21 is connected to the adapter 22.

The sleeve 88 is provided with a pair of circumferentially spacedinternal recesses 90 in which there are seated spring retainer members91 which are secured to the sleeve 88 by means of rivets 92. The bodyextension 82 is provided with an external recess 93 aligned with eachrecess 90 and overlapping the forward portion thereof. This results inthe formation of a shoulder 94 behind which the associated spring 91engages and prevents the forward movement of the sleeve 88 to the right,as viewed in FIGURE 8. A socket 95 opens through the body extension 82at the forward end of each recess 93. The socket 95 carries a ball 96which bears against the spring 91 and which projects inwardly throughthe body extension 82. When the ball 96 is moved outwardly, itsassociated spring retainer member 91 is sprung outwardly so as to clearthe shoulder 94 so that the sleeve 88 may be moved to the right. Inorder to facilitate the manual retraction of the sleeve 88 to the left,a plurality of circumferentially spaced grip members 97 are secured tothe rear portion of the sleeve 88 by means of fasteners 98, as is bestshown in FIGURES 1 and 2.

Reference is now made to FIGURES 1 and 5, wherein it is shown that thesleeve 88 is provided with a rearwardly extending rod 100 to which thereis connected a fitting 101. The fitting 101, in turn, has connectedthereto a rod 102 which is sectional and adjustable in length. The rearpart of the rod 102 is supported for sliding movement by means of abracket 103 in the manner best illustrated in FIGURE 5. The crank 41 hasa notch 104 formed therein for receiving the rear end of the rod 102.Thus, when the sleeve 88 is in its normal retracted position, the rod102 is seated in the notch 104 and prevents rotation of the'crank 41 toa position wherein the valve member 26 will be moved to an openposition. Thus, until such time as the sleeve 88 is moved to the right,the valve member 26 cannot be moved to an open position. Movement of thesleeve 88 to the right is prevented by the spring retainer members 91until such time as the nozzle 21 is in a position to 6 be coupled to theadapter 22. It will also be apparent that the sleeve 88 cannot bereturned to its position of FIGURES 2 and 8 until such time as the crank41 has been swung to a valve closing position.

Reference is now made to FIGURE 4, wherein the nozzle 21 is illustratedas being coupled to the adapter 22. It is to be noted that in thecoupled position of the nozzle 21 and the adapter 22, the balls areseated in the groove 68 and that outward movement of the balls 85 isprevented by the sleeve 88 which is in a forwardly projected position.It is also to be noted that the balls 96 have ridden up on the flatportion 65 of the collar 47 and hold the spring retainer members 91 intheir outwardly disposed sleeve releasing positions. The valve member 26has engaged the valve member 58 and the two have moved to the right to apartially opened position. It is to be noted that the valve member 26serves as the means for opening the valve member 58.

In assembling the nozzle 21 and the adapter 22, the nozzle 21 is movedrelative to the adapter 22 after the two have been aligned. The balls 85first ride up over the cam 64 onto the flat portion 65. Furthertelescoping of the nozzle 21 and the adapter 22 results in the balls 85riding up on the cam 66 and onto the flat portion 67. As the balls 85ride up onto the flat portion 67, the balls 96 ride up on the cam 64 andonto the flat portion 65 so as to move the spring retainer members 91 topositions where they release the sleeve 88. The sleeve 88 can still notbe moved to the right since the balls 85 are disposed outermost due totheir engagement with the flat portion 67. However, further telescopingmovement of the nozzle 21 relative to the adapter 22 will result in thealignment of the balls 85 with the groove 68 so that the balls 85 mayseat in the groove 68. The sleeve 88 may then be moved to the right andin this position, illustrated in FIGURE 4, serves to prevent the outwardmovement of the balls 85, thereby retaining the balls 85 in the recess68 and effecting the locking of the nozzle 21 to the adapter 22.

At this time, it is pointed out that when the nozzle 21 is initiallyengaged with the adapter 22, the sealing ring '75 is closely adjacentto, but spaced from the valve seat 51 of the collar 47. This permits thenozzle 21 to swivel relative to the adapter 22 without any scuffing orwearing of the sealing ring 75. When the hose of which the nozzle 21 isa part is finally settled and the fueling operation is about tocommence, the valve member 26 may be moved to its open positionutilizing the crank 41. As the valve member 26 moves to the right, thesprings 81 react on the nose 70 and move it to the right to spring urgethe sealing ring 75 into engagement with the valve seat 51 and thus formthe desired seal between the nozzle 21 and the adapter 22, the sealbeing accomplished after the movement of the nozzle 21 relative to theadapter 22 has been discontinued, thereby preventing any wearing orscufiing of the sealing ring 75.

When the fueling operation has terminated, the sleeve 88 cannot bewithdrawn to the left to release the nozzle 21 until the valve member 26has been moved back to its nozzle sealing position through the actuationof the crank 41 because of the interlock between the rod 102 and thecrank 41 described above. As the valve member 26 moves from right toleft, as viewed in FIGURE 4, the spring loading of the valve member 58results in the valve member 58 moving towards the valve seat 51 and inengagement therewith prior to the seating of the sealing ring 27 and thevalve member 26 on the valve seat 74 formed on the nose 70. As the valvemember 26 is further retracted, the nose 70 is moved rearwardly so thatthe sealing ring 75 will move out of engagement with the valve seat 51.The sleeve 88 may then be retracted and the nozzle 21 removed from theadapter 22.

Reference is now made to FIGURES 6, 7 and 8, wherein the details ofmeans for assuring the proper coupling of a nozzle to the correctadapter are illustrated.

The nozzle 21 is provided with a selector ring 105 which is mounted onthe sleeve 88, as is best shown in FIGURE 8. The selector ring 105 has arelatively thick flange 106 disposed at the right end thereof. Theflange 106 is provided with a set of three bores 107 which are spacedgenerally equidistant apart, although the pattern of the bores 107 couldbe varied if desired. In addition to the bores 107, the selector ring105 is provided with six other bores 108, three of the bores 108 beingdisposed on one side of the uppermost ones of the bores 107 and theother three of the bores 108 being disposed on the other side of theuppermost bore 107, as is best shown in FIGURE 6. The bores 108 arenumbered on the face of the adapter ring 105. As is best shown in FIGURE6, each of the bores 108 is provided with a reduced threaded extension109 for the reception of a bolt 110, the bolt 110 normally carrying asleeve 111 so that the head of the bolt 110 is disposed generally flushwith the end or face of the selector ring 105. It is intended that eachof the bores 108 with the exception of one has a bolt 110 therein. Thus,only one of the bores 108 is available to receive a pin in a manner tobe described hereinafter.

The adapter 22 is also provided with a selector ring arrangement, theflange 46 forming the selector ring. The flange 46 is provided withthree pins 112 in the form of cap screws which have the heads thereofprojecting to 7the left of the flange 46 for engagement in the bores Theflange 46 has a plurality of threaded bores 113 which are spaced onopposite sides of the uppermost pin 112. The bores 113 selectivelyreceive a pin 114 which, like the pins 112, is in the form of a capscrew. Each pin 114 also carries a sleeve 115, as does each of the pins112. The bores 113 are numbered in accordance with the sockets 108 inthe selector ring 105. It is to be noted that the pin 114 appears in thebore 113 which is aligned with the socket 108 in which there is no pin110. Thus, the nozzle 21 can be coupled to the adapter 22. On the otherhand, should the position of the pin 114 not match the empty one of thesockets 108, then, the nozzle 21 could not be moved sufiiciently overthe adapter 22 to effect the necessary coupling. In this manner, theproper fuel for the proper tank is assured.

Reference is now made to FIGURES 10 through of the drawings, wherein amodified nozzle and adapter assembly is illustrated. The assemblyincludes a nozzle, generally referred to by the numeral 121, and anadapter, generally referred to by the numeral 122.

The nozzle 121, as is best illustrated in FIGURE 11, includes a nozzlebody 123 having a curved flow passage 124 therethrough. The upper orleft end of the nozzle body 123 is provided with means, as at 125, tofacilitate the connection of a hose thereto.

The forward or right end of the nozzle body 123 is provided with a nose,generally refered to by the numeral 126. The nose 126 has a forwardportion 127 with an interior surface corresponding generally to theinterior surface of the forward part of the nozzle body 123. The rearportion of the nose 126 is outwardly oifest, as at 128, and istelescoped over the forward portion of the nozzle body 123. The rearportion 128 terminates in an outwardly directed flange 129. The rearportion of the nose 126 is sealed to the nozzle body 123 by means of asealing ring 130.

The forward portion of the nozzle body 123 is provided with a pair ofbores 131 in which there are seated balls 132. Each bore 131 also has aspring 133 therein bearing against the respective ball 132 and urgingthe ball 132 to the right and into engagement with the flange 129. Thus,the nose 126 is spring loaded for movement to the right.

As is best shown in FIGURE 17, the nose 126 carries on the outer forwardpart thereof a projecting sealing ring 134 whose purpose will bedescribed hereinafter. The sealing ring 134 is held in place on-the nose126 by a retainer 135 which is, in turn, held in place by a ring.136.The forward or right end of the flow passage 124 is normally closed by avalve member 137 which has a sealing ring 138 disposed in engagementwith the forward inner corner of the nose 126, as is best shown inFIGURE 17. As is best shown in FIGURE 11, the valve member 137 iscarried at the forward end of a valve rod 140 and with the housingportion 144 in defining the cavity 145.

The nozzle body 123 has a sleeve portion 148 disposed between the cavity145 and the fuel passage 124. The sleeve 148 is closed by a bushing 149which is sealed to the nozzle body 123 by a sealing ring 150. Thebushing 149 isalso sealed to the valve rod 140 by a sealing ring 151.The bushing 149 is retained in the sleeve 148 by the cover 146.

As is best shown in FIGURES 10 and 11, a shaft 152 extends transverselythrough thecavity 145 and is suitably journaled for rotation within thehousing portion 144 of the nozzle body 123. A crank 153 is secured toone end of the shaft 152 for manually rotating the same. The crank 153includes a handle or grip portion 154.

A cam 155 is carried by the center part of the shaft 152 and within thecavity 145, as is best shown in FIG- URE 11. The cam 155 has a cam track156 in which a follower 157 is mounted. As is best shown in FIGURE 10,the follower 157 has the ends thereof journaled in bearing members 158carried by the clevis 160. The clevis 160 is connected to the rear endof the valve rod 140 by means of a pin 161. It will be readily apparentupon viewing FIGURE 11 that when the crank 153 is swung downwardly in acounterclockwise direction, the cam 155 will be so rotated that thevalve rod 140 will move from left to right and thus move the valvemember 137 to a position opening the forward or right end of the flowpassage 124.

Reference is now made to FIGURES 12 and 16, wherein the details of theadapter 122 are illustrated. The adapter 122 includes an adapter body162 having a mounting flange 163 at the right end thereof, as viewed .inFIGURE 12. The mounting flange 163 may be connected either to a hydrantor to a tank. The adapter body 162 is provided at the left end thereofwith a second flange 164.

A ring 165 is disposed adjacent the flange 164 and is secured to theflange 164 by a plurality of fasteners 166 which are threaded intocircumferentially spaced projecting portions of the flange 164, as isbest shown in FIG- URES 12 and 16. The ring 165 has a flange portion 167which opposes the flange 164 and is sealed relativethereto by means of asealing ring or gasket 168, as 1s best shown in FIGURE 20.

A shroud 169 is centered within the adapter body 162 and is supported bya plurality of elongated bolts 170.

The bolts 170 pass through the flange portions 171 of the shroud 169 andare retained into the ring 165, as is best shown in FIGURE 12. The bolts170 carry elongated sleeves 172 which function as spacers and supportthe.

shroud 169 in spaced relation with respect to the ring 165.

The ring 165 has an inwardly projecting portion defining a valve seat173. The valve seat 173 has associated therewith a valve member 174. Thevalve member 174, as is best illustrated in FIGURE 20, carries a sealingring 175 which is held in place by a clamping ring 176 which, in turn,is secured to the valve member 174 by a plurality of fasteners 177.

A tubular guide member 178 projects to the right from .9 the rear orright side of the valve member 175. The guide member 178 projectsslightly into the shroud 169 and is held in place on the valve member174 by a large diameter coil spring 180 which surrounds the guide member178. The coil spring 180 bears against a shoulder 181 formed in the rearinterior portion of the shroud 169. Since the shroud 169 is fixedagainst movement, the spring 180 resists unseating movement of the valvemember 174 to the right.

The adapter member 122 also includes a connecting sleeve or collar 182.The sleeve 182 is threaded on to the left part of the ring 174, as at183. The sleeve 182 is of a circular cross-section and includes a leftsloping or cam portion 184 which terminates at its right edge in a flatportion 185. The flat portion 185 leads into a second sloping or camportion 186 which, in turn, terminates in a narrow flat portion 187. Arecess or groove 188 is disposed to the right of the flat portion 187.

Reference is again made to FIGURE 11 wherein it is shown that the nozzlebody 123 has an extension, generally referred to by the numeral 189. Theextension 189 has an enlarged rear portion 190 into which there isthreaded a plurality of bolts 191 which pass through an outwardlyprojecting flange 192 of the nozzle body 123.

The forward portion of the extension 189 is provided with a plurality ofcircumferentially spaced sockets 193 in which there are received balls194. The sockets 193 are so shaped that the inward movement of the balls194 is restricted. The balls 194 are intended to be seated in the groove188 and to lock the nozzle 121 to the adapter 122. The nozzle body 123also includes an internal annular abutment 179 in axially opposedrelationship to the flange 129 of the nose 126 for preventing theseparation of the nose 126 from the nozzle body 123 under the biasingforces of the springs 133 when the valve 26 is open.

A connection assuring sleeve or collar 195 is carried by the extension189 for longitudinal sliding movement. The sleeve 195 is provided withtwo enlargements 196 on the rear portion thereof. In each of theseenlargements there is formed a rearwardly opening bore 197 in whichthere is positioned a pressure exerting tubular member 198. A coilspring 200 is also disposed in each bore 197 and has the left endthereof received in the member 198. The member 198 bears against theflange 192 and serves to urge the sleeve 195 to the right to itscoupling assuring position.

The inner right portion of the sleeve 195 is recessed, as at 201. Theballs 194 are aligned with the recessed portion 201 and certain of theballs 194 normally engage the sleeve 195 in the recessed portion 201 toprevent movement of the sleeve 195 to the right.

As is best shown in FIGURE 17, each of the enlargements 196 also definesa relatively large cavity 202 which opens inwardly towards the extension189. In each cavity 202, there is pivotally mounted a latch member 203on a pivot pin 204. The latch member 203 has a right hand portion ofreduced thickness which is in the form of a stop 205. The stop 205 isnormally seated in an annular recess 206 in the exterior of the sleeve189, with the recess 206 having a forward edge portion in the form of ashoulder 207 against which the stop 205 engages to also normally preventmovement of the sleeve 195 to the right. It is the latch member 203which primarily functions to retain the sleeve 195 from moving to theright against the urgence of the springs 200.

The extension 189 is provided with a socket 208 aligned with each of thelatch members 203. A ball 209 is seated in each of the sockets 208 andbears against the inner surface of its associated latch member 203. Thesockets 208 are so formed wherein the balls 209 thereof are limited intheir inwardly movement.

Each of the latch members 203 is provided with an outwardly openingsocket 210 in which there is seated a spring 211 and a ball 212, theball 212 projecting partially from the socket 210 and bearing againstthe inner surface 10 of the enlargement 196. The spring 211 serves tourge the stop portion 205 of each latch member 203 to a latchingposition.

In FIGURE 13, the nozzle 121 is shown assembled with the adapter 122.Further, in the upper portion of this view, the extension 189 and thesleeve are shown rotated approximately 10 degrees so that the details ofone of the latches 203 are also shown. Thus, it will be seen that whenthe nozzle 121 is connected to the adapter 122, the balls 194 are seatedin the groove 188 and lock the nozzle 121 to the adapter 122. The slevee195 has slid forward under the influence of the springs 200 and theinner surface of the sleeve 195 prevents the balls 194 p from movingoutwardly out of the recess 188. At this time, the latches 203 play nopart in the operation of the device.

In FIGURE 13, the valve member 137 is also illustrated in a partiallyopen position. The valve member 137 has moved to the right from itsseated position and has engaged the valve member 174 of the adapter 122and moved the same from its seated position. It is to be understood thatthe valve members 137 and 174 will be moved further to the right whenthe nozzle 121 is operating at its full capacity. At that time, thevalve member 174 is substantially seated against the shroud 169. It isalso pointed out that although fuel flow is from the adapter 122 to thenozzle 121, the fuel flow may equally as well be from the nozzle 121 tothe adapter 122.

In order to facilitate the handling of the nozzle 121, a handle 213 isprovided, as is shown in FIGURES l0 and 14. The handle 213 does notextend through a full circle, the handle being interrupted adjacent thetop of the nozzle 121. The handle 213 is supported by three brackets 214which are clamped about the handle 213 in the manner best illustrated inFIGURE 11. Each of the brackets 214 is secured to the flange 192 of thenozzle body 123. The lowermost bracket 214 utilizes one of the bolts 191which secure the extension 189 to the flange 192. Others of the brackets214 are secured in place by other bolts 215 also passing through theflange 192.

As is clearly shown in FIGURES 10 and 14, the sleeve 195 is providedwith a pair of outwardly directed projections 216. These projections 216are disposed in transverse alignment. The purpose of the projections 216is to provide a gripping surface by means of whichone may grasp theprojections 216 and the handle 213 simultaneously to pull the sleeve 195to a position wherein the nozzle 121 can be released from the adapter122.

Reference is now made to FIGURES l0 and 18, wherein it is shown that oneof the projections 216 has a fitting 217 secured thereto by means offasteners 218. A sectional rod 220 which is adjustable in length has oneend thereof secured to the fitting 217. The rod 220 is guided adjacentits connection with the fitting 217 by being passed through a projectingcar 221 on the nozzle body 123. The left portion of the rod 220, asviewed in FIGURE 10, is passed through a projecting ear 222 also formedon the nozzle body 123 and is supported thereby. The hub which takes upslack in the span of the film intermediate portion of the crank 153 isprovided with a notch 223 in which the end of the rod 220 remote fromthe fitting 217 may seat. Thus, when the ring 195 is in its normalretracted position, the rod 220 projects into the notch 223 and preventsrotation of the crank 153. On the other hand, when the crank 153 is in aposition to hold the valve member 137 in an open position, the rod 220cannot move as far as is necessary to the left, as viewed in FIGURE 10,to permit the retraction of the sleeve 195 so that the nozzle 121 may bedisconnected from the adapter 122. In other words, until such a time asthe nozzle 121 is fully connected to the adapter 122, the crank 153cannot be rotated to move the valve member 137 to an open position, anduntil such time as the crank has returned to a position moving the valvemember 137 to its closed position, the sleeve 195 cannot be retracted torelease the nozzle 121 from the adapter 122.

When the nozzle 121 is being coupled to the adapter 122, the extension189 is initially partially telescoped over the sleeve 182 of the ada ter122. As the extention 189 is further telescoped over the sleeve 182, theballs 194 ride up the cam surface 184 and onto the flat surface 185. Onoutward movement the balls 194 engage against the rear cam surface 224of the recessed portion 201 of the sleeve 195 and urge the sleeve 195slightly to the left. sion 189 over the sleeve 182 results in the balls194 riding up the cam surface 186 onto the flat surface 187 wherein thesleeve 195 is further urged to the left. When the sleeve 195 is in thisposition, the stop portions 205 of the latches 203 are released from theshoulders 207 and may be easily swung outwardly to released positions.As the balls 194 ride up onto the flat portion 187, the balls 209 rideup the cam 184 and urge the latch members 203 to released positions.Then, as the nozzle 121 is further moved into engagement with theadapter 122, the balls 194 drop into the groove 188 to form the desiredinterlock between the nozzle 121 and the adapter 122. Since the latches203 are in their re leased position, as soon as the balls 194 drop intothe recess 188, the sleeve 195 slides forward and holds the balls 194 inthe recess 188 to prevent accidental disengagement of the nozzle 121from the adpater 122.

It is pointed out that during this initial interlock of the nozzle 121with the adapter 122, the sealing ring 134 is disposed closely adjacentto, but spaced from, the ring 165 so that the nozzle 121 may swivel withrespect to the adapter 122. However, when it is desired to have fuelflow through the nozzle 121 and the nozzle 121 is in its final positionrelative to the adapter 122, as the valve member 137 is moved to theright to its open position, the nose 126 is released by the valve member137 and it is urged to the right by the springs 133 so that the sealingring 134 is moved into compressive engagement with the ring 165, therebyforming the necessary seal between the nozzle 121 and the adapter 122.

It is to be noted that the sleeve 195 has a resilient ring 225thereabout. The resilient ring 225 protects the end of the nozzle 121when it is dropped or laid on the ground. Incidentally, in the event theselector ring 105 is not used in conjunction with the nozzle 21, thesleeve 88 of the nozzle 21 may be provided with a similar resilientbumper ring.

At this time, it is also pointed out that each of the nozzles andadapter may be provided with suitable dust covers to prevent theentrance of foreign matter into the mechanism thereof. These dust coversmay be of any simple type and are normally retained on their re-'spective components either by friction or a simple lug type interlock.Also, the dust covers will normally be permanently connected to theirrespective members by means of chains.

From the foregoing, it will be seen that novel and advantageousprovision has been made for carrying out the desired end. However,attention is again directed to the fact that variations may be made inthe example apparatus disclosed herein without departing from the spiritand scope of the invention, as defined in the appended claims.
